Out of order
Article Abstract:
The observation of galaxies by the Hubble Space Telescope (HST) has complicated the classification of objects in galaxies by suggesting that the morphology of galaxies changes systematically with look-back time similar to people. Like humans young galaxies develop fast, gain mass from mergers with lesser galaxies and from inflow of gas then grow old slowly as their structure relaxes and their stellar content ages and evolves.

A story of singular degeneracy
Article Abstract:
The lately discovered source of low-energy X-rays has proved that the formation of Ia supernovae followed the phenomenon of singular degeneracy that causes the explosion of the white dwarf. Ia supernovae are very important objects in cosmology, as it can be mainly used for measuring the expansion history of the Universe.
